I-HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Okokuqala, ukusetshenziswa kwamandla ekukhiqizweni komoya-mpilo kanye nezindleko zokusebenza kuphansi
Enqubweni yokukhiqiza umoya-mpilo, ukusetshenziswa kukagesi kubalwa ngaphezu kuka-90% wezindleko zokusebenza. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza umoya-mpilo we-pressure swing adsorption, ukusetshenziswa kwawo kwamandla e-oxygen ahlanzekile kwehle kusuka ku-0.45kW·h/m³ ngawo-1990 kuya ngaphansi kuka-0.32kW·h/m³ kulezi zinsuku. Ngisho nasekukhiqizweni komoya-mpilo we-cryogenic okukhulu, ukusetshenziswa kwamandla e-oxygen ahlanzekile aphansi kakhulu kungama-0.42kW·h/m³. Uma kuqhathaniswa nobuchwepheshe bokukhiqiza umoya-mpilo we-cryogenic, ubuchwepheshe bokukhiqiza umoya-mpilo we-pressure swing adsorption bunezinzuzo ezisobala zezindleko ezimweni zokusebenza lapho amabhizinisi engenasidingo se-nitrogen futhi inqubo yokusebenzisa umoya-mpilo ayinazo izidingo eziphezulu zokuhlanzeka komoya-mpilo kanye nokucindezela.
Okwesibili, inqubo ilula, ukusebenza kuyaguquguquka, futhi kulula ukuqala nokuma
Uma kuqhathaniswa nobuchwepheshe bokukhiqiza i-oxygen e-cryogenic, ukukhiqizwa kwe-oxygen e-pressure adsorption kunenqubo elula. Imishini yamandla eyinhloko yi-Roots blower kanye ne-Roots vacuum pump, futhi ukusebenza kulula futhi kulula ukuyinakekela. Njengoba kungekho nqubo yokupholisa noma yokushisa ngesikhathi sokuqala nokuvala imishini yokukhiqiza i-oxygen e-pressure adsorption, ukuqala kokuqala kuthatha imizuzu engama-30 kuphela ukukhiqiza i-oxygen efanelekile, kanti ukuvala kwesikhathi esifushane kuthatha imizuzu embalwa kuphela ukukhiqiza i-oxygen. Ngaphezu kwalokho, ukuvala idivayisi kulula, kudinga kuphela ukuvala imishini yamandla kanye nohlelo lokulawula. Uma kuqhathaniswa nokukhiqizwa kwe-oxygen e-cryogenic, ubuchwepheshe bokukhiqiza i-oxygen e-pressure adsorption adsorption bulula kakhulu ukuqala nokumisa, kunciphisa kakhulu izindleko zokusebenza ezitholwa ngesikhathi sokuqala nokuvala imishini.

Okwesithathu, idinga utshalomali oluncane futhi inesikhathi esifushane sokwakha
Ukugeleza kwenqubo yedivayisi yokukhiqiza i-oxygen yokucindezela i-adsorption swing kulula, ikakhulukazi yakhiwe uhlelo lwamandla, uhlelo lokufaka i-adsorption kanye nohlelo lokushintsha ama-valve, njll. Inani lemishini lincane, okungonga izindleko zokutshalwa kwezimali kanye kuphela kwemishini. Idivayisi ithatha indawo encane, okunganciphisa izindleko zokwakha zedivayisi kanye nezindleko zomhlaba wokwakha. Umjikelezo wokucubungula nokukhiqiza wemishini umfushane kakhulu. Umjikelezo wokucubungula wemishini eyinhloko ngokuvamile awudluli izinyanga ezine. Ngaphansi kwezimo ezijwayelekile, isidingo sokukhiqiza i-oxygen singafinyelelwa zingakapheli izinyanga eziyisithupha. Uma kuqhathaniswa nesikhathi sokwakha esicishe sibe unyaka owodwa sokukhiqizwa kwe-oxygen e-cryogenic, isikhathi sokwakha sedivayisi sincishiswe kakhulu.
Okwesine, imishini ilula futhi kulula ukuyinakekela
Imishini esetshenziswa kubuchwepheshe bokukhiqiza i-oxygen yokushutheka kokucindezela, njengama-blower, amaphampu e-vacuum kanye nama-valve alawulwa uhlelo, konke kungakhiqizwa ekhaya. Ukushintsha izingxenye ezisele kulula, okunganciphisa izindleko futhi kwenze isikhathi sokwakha sibe lula ukusilawula. Ukugcinwa kwemishini kulula futhi insizakalo yangemva kokuthengisa ilula. Uma kuqhathaniswa nokugcinwa kwama-compressor amakhulu e-centrifugal asetshenziswa ekukhiqizeni i-oxygen e-cryogenic, abasebenzisi bokukhiqiza i-oxygen yokushutheka kokucindezela akudingeki batshale imali eningi yokulungisa noma baqashe abasebenzi bokulungisa abangochwepheshe.

Iphuzu lesihlanu ukuthi ukulawulwa komthwalo kulula
Uma kuqhathaniswa nobuchwepheshe be-cryogenic liquid oxygen, ukukhiqizwa kwe-oxygen yokumunca ingcindezi yokumunca kungafinyelela ukulungiswa okusheshayo kokukhipha kanye nobumsulwa ngokushintsha okuncane ekusetshenzisweni kwamandla e-oxygen ahlanzekile. Umphumela ojwayelekile ungalungiswa phakathi kuka-30% no-100%, kanti ubumsulwa bungalungiswa phakathi kuka-70% no-95%. Ikakhulukazi uma kusetshenziswa amasethi amaningana amadivayisi okukhiqiza i-oxygen yokumunca ingcindezi yokumunca ingcindezi ngesikhathi esifanayo, ukulungiswa komthwalo kulula kakhulu.
Okwesithupha, inezinga eliphezulu lokuphepha kokusebenza
Ngenxa yokuthi ukukhiqizwa komoya-mpilo okwenziwa yi-pressure swing adsorption kuwumsebenzi ophansi wokucindezela ekamelweni lokushisa futhi ngeke kube khona izinto ezifana nokucebisa umoya-mpilo owuketshezi kanye ne-acetylene, kuphephile uma kuqhathaniswa nokusebenza kokushisa okuphansi kanye nokucindezela okuphezulu kokukhiqizwa komoya-mpilo ocijile.

Uma unezidingo ze-oxygen/nitrogen, sicela uxhumane nathi:
